SPECIFICATION forming part of Letters Patent No. 667,343, dated February5, 1901.

Application filed October 19,1900. Serial No. 33,553. (No model.)

T0 all whom it may concern.-

Beit known that I, JAMES E. SAGUE, a citizen of the United States,residing at Schenectady, in the county of Schenectady and State of NewYork, have invented certain new and useful Improvementsin Locomotives,ofwhich the following is a specification.

This invention relates to that class of locomotives in which thefire-box is made of extra width in order to obtain an ample grate areawithout unnecessarily increasing the length thereof. It is desirablethat the vfire box should be located at the rear of the locomotive inorder that the fireman and engineer may be together. In such locomotivesit is necessary to provide one or more pairs of su pporting or trailing`wheels under the fire-box, and in order to obtain the greatest width oftire-box and ash-pan the sides of the ash-pan should be brought as closeas possible to the inner sides of the trailing wheels. In the locomotivehereinafter described the axle-boxes of the trailing wheels are arrangedoutside of the truck-frame, by which construction the sides of theash-pan may be arranged close to the inner sides of the trailing wheels,thus giving to the ash-pan a greater width than could be obtained wherethe axle-boxes are arranged inside the wheels. Such an arrangement alsoprevents the journals of the trailing wheels from being heated by closeproximity to the ash-pan. The bearings are readily accessible foroiling, &c., and the lateral distance between the points of support isincreased, thus making the engine much steadier and freer from atendency to roll, as is the case where the axle-boxes are arrangedinside the wheels.

While, broadly stated, it is not new to arrange the axle-boxes oftrailers outside the wheels, it is new to so arrange the axle-boxes inconnection with the improved devices employed by me for equalizing theweight, as hereinafter described. The equalizing mechanism is of animproved construction and arranged in an improved way. Springs areattached to the axle-boxes of the drivin g-wheels and the trailers, andthey are connected together by links and levers arranged in an improvedway and 'in such manner as to properly distribute the weight. Theaxle-boxes of the driving-wheels are arranged inside the truck-frame,and special mechanism is employed by me for connecting the springsattached to the axle-boxes of the drivers with the springs attached tothe axle-boxes of the trailing wheels, which, as before stated, arearranged outside the truck-frame.

The details of construction will be hereinafter more fully described.

The subject-matter deemed novel will be set forth in the claims.

In the accompanying drawings, Figure/l shows a side elevation ofalocomotive embodying my present invention. Fig. 2 is a plan View of thetruck thereof. Fig. 3 is a detail view showing particularly the mannerof connecting the springs of the drivers with the springs of thetrailing wheels. Fig. 4 is a detail plan View of this mechanism, andFig. 5 shows a transverse section on the line 5-5 of Fig. 3.

The boiler A and cab B, with their appurtenances, are of usualconstruction. The fire-box Al and ash-pan A2 are mounted on a framesupported on driving-wheels C, trailing Wheels D, and pilot-wheels E.The main frame is preferably continuous,the front ends of the sidepieces H thereof being secured to a buffer F, while the rear ends areconnected by a cross-frame G. The frame H is formed with pedestals orguides H3 H4 for the boxes c of the drivingwheels. Outside frame piecesor plates J are provided, and they have each a guide or pedestal dextending over the axle-box of the corresponding trailer. These framepieces or plates J are arranged outside the vrvertical plane of thetrailing wheels over the trailing axle, and the rear ends of theframe-pieces H also extend over the trailing axle inside the wheels, asindicated, for instance, in Fig. 2. Filling-pieces K are interposedbetween the outside framepieces Jand t-he adjacent sides of theframepieoes H and are bolted thereto. The outside frame-pieces J and therear ends of the main fra me-pieces H are also connected togetherbetween the cross-frame G and the trailing axle by means of bolts.Filling-pieces G' are interposed between the rear ends of the f' ri667,343

outside plates J and the rear ends of the framepieces I-I and aresecurely bolted thereto and to the cross-frame G, as indicated.

The construction which I have v just described is not herein claimed aspart of my present invention, as substantially the same construction isshown and claimed in my applioation for patent, Serial No. 26,779, filedAugust 13, 1900. That application, however, shows different mechanismfor equalizing the weight or connecting the springs of the drivers withthe springs of thetrailing Wheels.

In the-present instance a spring M is mounted on top of the axle-box ofeach trailing Wheel. The rear end of each spring is conneet-ed with thecorresponding outside lframepiece .I by means of a link fm. The frontend of each spring M is connected by means of a link N withalever O,secured to ashort rockshaft P, mounted in bearings in a hanger Q,depending from the truck-frame. The lever O is parallel with theframe-pieces J and H, and it is arranged outside the vertical plane ofboth frames. The short rock-shaft P extends inwardly beneath theframe-pieces J and H, and to its inner end is secured a lever R, whichis arranged in the saine vertical plane as the springs S S', which areattached to the axle-boxes of the driving-wheels O. The lever R isconnected by means of links T with the rear end of the spring S of therear driving-wheel. This spring is shown as being mounted on top of theaxle-box of the rear driving-Wheel; but it may be otherwise attachedthereto. The arrangement on opposite sides of the locomotive isprecisely the same.

In the present instance, Where the springs S and S are mounted on top ofthe axleboxes of the driving-Wheels, the front end of each spring S isconnected, by means of links U, with a centrally-pivoted lever U', theopposite end of which is in turn connected by links u With the rear endof the spring S', while the front end of the spring S is connected, bymeans of links u', with a bracket on the main frame H. The arrangementot' the springs S and S and their connections is the saine on both sidesof the truck.

The arrangement of my improved equalizing mechanism enables me to securea large area of ash-pan. The ash-pan may be extended to its full lengthWithout interference With the equalizing mechanism. It is only necessaryto reduce the area of the ash-pan to accommodate the trailing axle. Thisarrangement also affords all the necessary space required forconveniently hanging and operating the brakes, While still connecting inan efficient manner the springs of the driving-Wheels with the springsof the trailing Wheels, which are,

1 as before stated, in different vertical planes.

I claim as my inventionl. The combination of the driving-wheels, theiraxles, the axle-boxes thereof arranged inside the wheels, the trailingwheels, their axles, the axle-boxes thereof arranged outside the Wheels,springs attached to the axle-boxes of the driving-Wheels and to theaxle-boxes of the trailing Wheels, the truck-frame, short rock-shaftsarranged in bearings thereon, le-

vers projecting from the outer ends of said y rock-shafts and connectedwith the front ends of the springs of the trailing wheels, and leversprojecting from the inner ends of said rock-shafts, and connected Withthe rear ends of the springs of the rear driving-Wheels.

2. The combination of the driving-Wheels, their axles, the axle-boxesthereof arranged inside the Wheels, the trailing Wheels, their axles,iheaxle-boxes thereof arranged outside the Wheels, springs attached tothe axle-boxes of the driving-Wheels and to the axle-boxes of thetrailing Wheels, the truck-frame, short rock-shafts arranged in bearingsattached to the truck-frame, levers projecting from the outer ends ofsaid rock-shafts and connected With the front ends of the springs of thetrailing Wheels, levers projecting from the inner ends of saidrock-shafts and connected with the rear ends of the springs of the reardriving-Wheels, a dre-box and an ash-pan projecting forwardly of thetrailing axle and having a maximum area infront of the trailing axle,substantially as described.

3. The combination of the inside main frame, the outside frame-pieces,the driving- Wheels, their axles, the axle-boxes thereof,

arranged inside the Wheels, the trailing wheels their axles, the axleboxes thereof arranged outside the outside frame pieces, springsattached to the axle-boxes on the driving-Wheels, and to the axle-boxesof the trailing wheels,short rock-shafts arranged in bearings attachedto the truck-frame, levers projecting from the outer ends of saidrock-shafts, and connected with the front ends of the springs of thetrailing Wheels, and levers projecting from the inner ends of therock-shafts and connected with the rear ends of the springs of the reardriving-Wheels.
